Question

I have two GridViews, the first works fine as I defined the datasource when I dropped it onto the asp page via visual studio and I specified the table to use.

The other GridView (dgvParams below) has just been dropped onto the asp page and I want to use it at run time:

Imports System.Data
Imports System.Data.SqlClient
Imports myDataBase

Partial Class TestWeb
    Inherits System.Web.UI.Page

    Dim data As New cDatabase

    Public Sub New()

    End Sub

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        dgvParams = New GridView

        LoadParamsGrid()
    End Sub

    Public Sub LoadParamsGrid()


        ' Create the dataset
        Dim strCon As String = data.DBConn.ConnectionString
        Dim strSQL As String = "dbo.GetParameters"
        Dim dataAdapter As New SqlDataAdapter(strSQL, strCon)
        Dim table As New DataTable

        Try
            dataAdapter.Fill(table)
        Catch ex As Exception
            ' try again
            dataAdapter.Fill(table)
        End Try

        dgvParams.DataSource = table
        dgvParams.DataBind()


    End Sub

End Class

When I step through the code I can see row and column counts are as expected and call “dgvParams.DataSource = table”.

I think I am missing another step somewhere so that I can physically see the data on the GridView? Any suggestions?

Thank you

I changed fro using a table to a dataset and it just “worked”… although not right away! Not sure really what made this work but this is what I am using now:

Dim ds As New DataSet

Try
    dataAdapter.Fill(ds)
Catch ex As Exception
    ' try again
    dataAdapter.Fill(ds)
End Try

dgvParams.DataSource = ds.Tables(0)
dgvParams.DataBind()
